1 (The nose and mouth make up the first part where air enters your body. 2  The trachea, or windpipe, is the second part and it delivers air to the lungs. 3  Your lungs are the third part where oxygen is absorbed by the blood, which brings it to the rest of the body. 4  Finally, the diaphragm is the fourth part.
The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli. The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from the inhaled air passes through the alveoli walls and into the blood.After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs.As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood.Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale.he bronchioles end in tiny balloon-like air sacs called alveoli.
